thanks all, i'm using xlite but it does not have automatic recording as the user has to click a recording button.
also i'm having trouble to register a voip on 3cx, the provider are using port 1710, any suggestings, thanks

You can supply the port when you add a new line (or change it for an existing one). Change the value in the Proxy Port (default is 5060) to 1710 and make sure that if you use a firewall it should allow traffic through this port (1710).
